Minnesota residents can now use an online map to see the radon levels in their counties.

The Minnesota Department of Health launched the map to encourage both homeowners and renters to test their homes for radon. The department says about two in five homes have dangerous amounts of radon, which they say is the leading cause of lung cancer among nonsmokers, causing more than 21,000 deaths each year in the United States.


Radon is an odorless, colorless gas that occurs naturally in Minnesota soils and can enter homes through cracks in the walls or foundations.

The map uses data from 2010 to 2014 with more than 86,000 properties tested.
